Question

I have 200 input field in my page. All are radio button of group of 5. How can I get the data of input field. Names of all input field are created dynamically from database.
My code is as follows
$attributes = array('class' => 'result', 'id' => 'result', 'name' => 'result');
echo form_open('exam/result',$attributes);
$a = array(
'name' => 'aptitude-'.$value->question_id,
'id' => 'answer1',
'value' => 'a',
'checked' => FALSE,
);
$b = array(
'name' => 'aptitude-'.$value->question_id,
'id' => 'answer2',
'value' => 'a',
'checked' => FALSE,
);
$c = array(
'name' => 'aptitude-'.$value->question_id,
'id' => 'answer3',
'value' => 'a',
'checked' => FALSE,
);
$d = array(
'name' => 'aptitude-'.$value->question_id,
'id' => 'answer4',
'value' => 'a',
'checked' => FALSE,
);
$e = array(
'name' => 'aptitude-'.$value->question_id,
'id' => 'answer5',
'value' => 'a',
'checked' => FALSE,
);
$f = array(
'name' => 'aptitude-'.$value->question_id,
'id' => 'answer6',
'value' => 'a',
'checked' => TRUE,
'style' => 'display:none'
);
echo form_radio($a);
echo form_label($value->a, 'a');
echo "<br>";
echo form_radio($b);
echo form_label($value->b, 'b');
echo "<br>";
echo form_radio($c);
echo form_label($value->c, 'c');
echo "<br>";
echo form_radio($d);
echo form_label($value->d, 'd');
echo "<br>";
echo form_radio($e);
echo form_label($value->e, 'e');
echo "<br>";
echo form_radio($f);
echo form_close();
This code will run for 200 times

Use array name aptitude[]:
$a = array(
'name' => 'aptitude['.$value->question_id.']',
'id' => 'answer1',
'value' => 'a',
'checked' => FALSE,
);
$b = array(
'name' => 'aptitude['.$value->question_id.']',
'id' => 'answer2',
'value' => 'b',
'checked' => FALSE,
);
$c = array(
'name' => 'aptitude['.$value->question_id.']',
'id' => 'answer3',
'value' => 'c',
'checked' => FALSE,
);
$d = array(
'name' => 'aptitude['.$value->question_id.']',
'id' => 'answer4',
'value' => 'd',
'checked' => FALSE,
);
$e = array(
'name' => 'aptitude['.$value->question_id.']',
'id' => 'answer5',
'value' => 'e',
'checked' => FALSE,
);
$f = array(
'name' => 'aptitude['.$value->question_id.']',
'id' => 'answer6',
'value' => 'f',
'checked' => TRUE,
'style' => 'display:none'
);
Get POST value:
$aptitudes = $this->input->post('aptitude');
print_r($aptitudes);
// example output
[7] => a
[5] => c
[3] => f
// where [7] [5] [3] are the $value->question_id
Get specific POST
$aptitudes[5]; // output => c
